Wife doesnt wants to give divorce

Hello, My married this girl through matrimonial website and it was an arrange one, I'm resident of mumbai and she is from delhi, so the marriage happened in delhi and the expense of marriage was paid by them and few gifts to my mother & sister. She couldnt adjust with my family and was in & out of home after marriage, later on I had to take a step to stay separately with her after 2 years trying to adjust in family. Now after staying separately from family for two & half years I still not able to adjust to her tantrums, she doesnt like me going to my family talking to them or going out with them etc etc. Now she has started fighting regularly torturing me and not ready divorce even though staying together is hell. We do not have children and do not plan also. She does some kind of black magic also, she very dependent of astrology and doesnt wish to listen or stay according to me. She just wants to stay with me to take revenge it seems, since she doesnt loves but doesnt wants to end it also. She is working with company as HR and uses her whole salary on ownself, never helped to family cores or rent etc. My family home is under the name of my mother and my sister is staying with my mom after her divorce. She threatens to complain against my family in case I go ahead with divorce. Kindly suggest some good resolution.
